Quadruple evaluation means that the rising and falling edges of A and B
are evaluated; whether up or down count pulses are generated depends on
which channel hurries first.
In this counting mode I+0.0 and I+0.1 have the following function:
I+0.0 as channel A: If channel A hurries in front, the counter counts up.
I+0.1 as channel B: If channel B hurries in front, the counter counts down.

Every rising edge of A is evaluated. Channel B defines the counter
direction.
In this counting mode I+0.0 and I+0.1 have the following function:
I+0.0 as channel A: Clock pulse for the counter at rising edge.
I+0.1 as channel B: Defines the counter direction (0 = up, 1 = down)

The rising edges of channel A and B are evaluated. The counter is
incremented with every rising edge of A and decremented with every rising
edge of B.
In this counting mode I+0.0 and I+0.1 have the following function:
I+0.0 as channel A: Clock up pulse for the counter at rising edge.
I+0.1 as channel B: Clock down pulse for the counter at rising edge.
